Within the world of 3D Printing, there are so many different types of 3D Printer Filaments to choose from, with new polymers coming out almost monthly. One such example of this is black Flexible 1.75mm TPU Filament, which offers the unique characteristic of being flexible and durable against impacts and compression forces. With a shore hardness of between 90 and 98, this filament can be printed with an almost tyre-like feel, which can be “squished” quite dramatically while still reverting back to its original shape and form.
This flexible TPU filament is a polymer that utilises PLA as a base plastic, meaning it has very similar printing specifications to Standard PLA Filament. However, the added materials that give it the unique flexible traits means that the polymer does require some experimentation and practice to get just right. So, as a start, begin by raising the temperature of your hot end and heated bed by around 10 to 20 degrees, and set the machine to print at a slightly slower speed. From there, you will simply need to tweak the printing specifications until you are satisfied with the print quality, aiming for as little stringing and lifting as possible.
